My dish washer is cleaning ok as far as I can tell but it has become somewhat noisy. It sounds like it has marbles in it and has a humming sound that it makes for a second or two then stop for a second and does it again.
Clean out your sump pump and drain pump and hose…theres 4 video’s on a unit similar to you watch the video’s it should be helpful.

I cleaned out the Impeller area thinking it might be broken. It wasn’t broken owever there was some debri in there. I put it back together and it sound good again. thanks for responding.
The noise was during the was cycle. The sump doesn’t run during that time does it?
Yeah the sump is what washes your dishes
